Hydrological processes of lowland watersheds of the southern USA are not well understood compared to a hilly landscape due to their unique topography, soil compositions, and climate. This study describes the seasonal relationships between rainfall patterns and runoff (sum of storm flow and base flow) using 13 years (1964–1976) of rainfall and stream flow data for a low-gradient, third-order forested watershed. It was hypothesized that runoff–rainfall ratios (R/P) are smaller during the dry periods (summer and fall) and greater during the wet periods (winter and spring). We found a large seasonal variability in event R/P potentially due to differences in …

Knowledge of vegetation-atmosphere interactions has great importance in ecological research, and to recognize these effective interactions, the collection and interpretation of micrometeorological data are essential. The main goal of this study was to understand the trends of evapotranspiration (ET) and other micrometeorological parameters within the growing season above a Japanese red pine forest in Japan. To measure ET, the Bowen ratio-energy balance approach was employed. These measurements were used with the Penman-Monteith reference evapotranspiration (ET_0) in order to create crop coefficients (K_c) by the ratio of ET:ET_0. Mean daily ET on the dry and rainy days was found to be …
Assessment Of Yield And Water Use Efficiency Of Drip-Irrigated Cotton (Gossypium Hirsutum L.) As Affected By Deficit Irrigation, Fuad Hussein, Mussaddak Janat, Abdallah Yakoub
Assessment Of Yield And Water Use Efficiency Of Drip-Irrigated Cotton (Gossypium Hirsutum L.) As Affected By Deficit Irrigation, Fuad Hussein, Mussaddak Janat, Abdallah Yakoub

A field experiment was conducted for 2 consecutive years to evaluate the response of cotton crop to deficit irrigation under drip irrigation conditions. Water use efficiency (WUE), seed cotton yield, and fiber quality parameters were assessed at various irrigation levels. The experiment was set up to apply water at 4 different application rates: 50%, 65%, 80%, and 100% of the soil water depletion. These were abbreviated as DI50, DI65, DI80, and FI, respectively. The total amounts of irrigation water applied were 408 and 773 mm and the average seed cotton yields were 2909 and 5090 kg ha^{-1} for the DI50 …
