Abstract: Due to increasingly stringent regulations on the discharge of wastewaters as well as the decreasing availability of freshwater resources, there is a need to consider the expanded use and reuse of marginal quality waters ...

Abstract: This paper presents a brief history of irrigation and drainage related to ASCE activities on its Jubilee. This paper discusses legislation and policies that affect irrigation and drainage practices, water quality constituents ...

Abstract: On the west side of California's San Joaquin Valley, researchers are experimenting with agroforestry systems to help solve the agricultural drainage problem. Eucalyptus tree plantations are used to consume the shallow ...

Abstract: The mobility of trace elements in soil reflects the chemical reactivity of the elements in the soil matrix. The result is that trace‐element mobility is both specie and site dependent. An overview of selected geochemical ...

Abstract: The quality of an irrigation water, in both its total salinity and individual constituents, influences the chemical character of the soil solution and irrigation return flows including drainage waters. Dissolution, ...

Abstract: Part I of this paper presented a two‐dimensional dynamic finite‐element model of fluid flow and solute transport in root‐soil profiles with different root‐uptake mechanisms. Field data collected in 1989 were used to validate ...

Abstract: Eucalyptus trees are being recommended as a management option for lowering the shallow ground water and reusing saline subsurface drainage water in drainage‐impacted areas of the San Joaquin Valley in California. Both field ...

Abstract: Irrigation‐induced erosion and subsequent sediment loss is a serious agricultural and environmental problem. Recent recognition of this problem has stimulated the development and evaluation of erosion and sediment‐loss‐control ...

Abstract: The cultivation of eucalyptus trees is being recommended to lower the shallow ground‐water level and to reuse saline‐subsurface drainage waters from tile‐drained cropland in drainage‐impacted areas in California's San ...

Abstract: A finite element model to simulate salt flow and underdrainage for shallow water table conditions (presented in Part 1) is used to simulate two illustrative cases. The first case involves a one‐dimensional problem in which ...
