Impact of Tile Drainage on Evapotranspiration in South Dakota, USA, Based on High Spatiotemporal Resolution Evapotranspiration Time Series From a Multisatellite Data Fusion System

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Soil drainage is a widely used agricultural practice in the midwest USA to remove excess soil water to potentially improve the crop yield. Research shows an increasing trend in baseflow and streamflow in the midwest over the last 60 years, which may be ...

Seasonal surface drainage of sloping farmland : a review of its hydrogeomorphic impacts [PDF]

, 2015
The combination of runoff-generating areas (saturated soils) and overland flow concentration in features such as drainage ditches makes sloping farmland vulnerable to soil erosion.

Performance of Drought Indices for Ecological, Agricultural, and Hydrological Applications [PDF]

Earth Interactions, 2012
Abstract In this study, the authors provide a global assessment of the performance of different drought indices for monitoring drought impacts on several hydrological, agricultural, and ecological response variables. For this purpose, they compare the performance of several drought indices [the standardized precipitation index (SPI ...

The hydrologic behavior of agricultural watersheds

Eos, Transactions American Geophysical Union, 1944
During the past decade there has been much discussion, pro and con, with regard to the effects of agricultural operations upon the amount and regimen of runoff from watersheds. The problem becomes highly involved on large watersheds, because they are made up of various complexes of soil, cover, topography, and other edaphic features.

A weather generator for hydrological, ecological, and agricultural applications [PDF]

Water Resources Research, 2007
This paper presents a weather generator that allows simulation of hydrometeorological variables representative of a given geographic location: precipitation, total cloud cover, incoming shortwave radiation, air temperature, humidity, and wind speed. The approach captures the essential relationships among the quantities of interest, while modeling the ...
