Monitoring soil moisture is an alternate method to water-based balance methods of managing irrigation water. Using this method you can "see" what is going on in the soil and determine answers to some key irrigation management questions: Did enough water infiltrate the soil? Is too much water being applied? What is the water uptake pattern of the roots? When should irrigation take place? What was the depth reached by the irrigation? Includes 24 figures and 7 tables, metric conversions, and an appendix of typical root depths. One of a series of water management handbooks prepared by the UC Irrigation Program.

This book is written for all those involved in measurement of soil water phenomena, whether they be environmental scientists, field technicians, agronomists, meteorologists, hydrogeologists, foresters, physical geographers, civil or water engineers or students in these subjects. It contains a comprehensive description of all the major methods used for measurement of soil water content and potential, solute concentration, transport and balance of water and solutes, including recharge to groundwater aquifers. The emphasis is firmly on techniques which can be applied in the field or on samples obtained from the field. The theory and practice of the workings of the main instruments and methods available is described, along with practical tips on surmounting some of the main difficulties and explanations of many commonly encountered jargon words.

In recent years, the significance of water protection and conservation is still increasing. Information about the state of water in soil is a key component in soil water monitoring, irrigation control systems and its optimization. The purpose of this work is to create a wireless sensor network for the measurement of soil water potential. The work includes the description of measurement methods, selection of appropriate method and its calibration. It also contains hardware and firmware realization of the two types of wireless modules, the end station with sensors and the base station for data reception. The realized application contains a user program which allows data logging, displays actual data or past characteristics and changes the system settings with a possibility to request system for the necessary information.

Monitoring Water Quality is a practical assessment of one of the most pressing growth and sustainability issues in the developed and developing worlds: water quality. Over the last 10 years, improved laboratory techniques have led to the discovery of microbial and viral contaminants, pharmaceuticals, and endocrine disruptors in our fresh water supplies that were not monitored previously. This book offers in-depth coverage of water quality issues (natural and human-related), monitoring of contaminants, and remediation of water contamination. In particular, readers will learn about arsenic removal techniques, real-time monitoring, and risk assessment. Monitoring Water Quality is a vital text for students and professionals in environmental science, civil engineering, chemistry — anyone concerned with issues of water analysis and sustainability assessment. Covers in depth the scope of sustainable water problems on a worldwide scale Provides a rich source of sophisticated methods for analyzing water to assure its safety Describes the monitoring of contaminants, including pharmaceutical and endocrine disruptors Helps to quickly identify the sources and fates of contaminants and sources of pollutants and their loading

Soil moisture is a very important component of the land-atmosphere exchange. Practically, it is valuable in both the agricultural and meteorological industries. Farmers require soil moisture for crop yields, while the atmospheric numerical modeling community has found soil moisture to be extremely important in generating realistic forecasts. Physically, the soil moisture not only provides water vapor for precipitation through evapotranspiration and controls the splitting of net radiation into sensible and latent heat components, but it also provides thermal inertia to the climate through heat storage and release from large water reservoirs (Famiglietti et al. 1998). Quantification of soil moisture is challenging since the range of spatial scale varies from centimeters to thousands of kilometers, while temporal scales vary from minutes to months. In the short term, soil moisture is influenced by topography, soil type, texture, and vegetation and affects the infiltration of water into and through the soil, as well as how much water will be held within the soil. In the long term, soil moisture is impacted by atmospheric forcing and affects the amount of water available to the soil through rain (or snowmelt), as well as removal by evapo-transpiration (Entin et al. 2000). Due to the expense and difficulty of measuring soil moisture, few extensive data sets currently exist. Exceptions include those found in Russia (dating back to the 1930s), Mongolia (1973-1995), China (1981-1991), India (1987-1995), and the US (Illinois, Iowa and Oklahoma, from the early 1980s to the present), (Robock et al. 2000). Most of these data were taken several times per month and do not provide high-frequency variations in time. A real-time, operational monitoring network for soil moisture detection has very important ramifications in the satellite industry, where such measures could serve as a ground truth. This paper discusses a real-time soil monitoring station that has been established at the Savannah River Site (SRS), located in the southeastern US, which provides 15-minute average soil moisture data. The measurement technique is first discussed, along with characteristics of the observation sites. Several applications of the monitoring are then examined. This includes the use of soil moisture as a decision-making tool in performing prescribed fires of the local forest vegetation. Since soil moisture measurements are also very important in the proper determination of surface fluxes in atmospheric models, a comparison of these point measurements with the National Center for Atmospheric Predictions (NCEP) model simulations over an extended period of time are examined. Finally, simple expressions describing the temporal variation of the soil moisture with precipitation events at the SRS are discussed.

Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides: *practical guidelines on the soil physical measurements across a range of soils, climates and land uses; *straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and *guidelines on the interpretation of results and integration with land resource assessment. Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.
