Rainfall‐Reaeration Effects

Journal of Irrigation and Drainage Engineering, 1990
The effect of rainfall intensity on reaeration has not been adequately reported in the literature. It is clear that rainfall causes surface turbulence and increases reaeration, and a significant linear relationship (r = .97) was found in this study between rainfall intensity and KL(20), the corrected mass transfer rate at 20°C, an initial oxygen ...

Effective Rainfall Estimation Methods

Journal of Irrigation and Drainage Engineering, 1990
Numerous methods for estimating effective rainfall have been proposed in the past, including: direct measurement techniques; empirical methods; and soil water balance methods.

Effect of Maximum Rainfall Position on Rainfall‐Runoff Relationship

Journal of Hydraulic Engineering, 1991
The aim of this technical note is to evaluate the effect of the maximum precipitation of synthetical hyetograph on rainfall hydrograph generation. Fourteen intense storms of long duration are analyzed. The results show an important variation of the coefficient \Ir\N in relation to the rainfall duration.

The effects of rainfall on rainfall

Science, 2016
Atmospheric Science![Figure][1] In the United States, soil moisture in the east or west has opposite effects on future rainfall. PHOTO: GEORGE RANALLI/SCIENCE SOURCE Soil moisture, which is controlled in part by past rainfall, can affect the probability of future rainfall over large areas.

Effects of rainfall patterns on runoff and rainfall-induced erosion

International Journal of Sediment Research, 2019
Abstract Rainfall-induced erosion involves the detachment of soil particles by raindrop impact and their transport by the combined action of the shallow surface runoff and raindrop impact. Although temporal variation in rainfall intensity (pattern) during natural rainstorms is a common phenomenon, the available information is inadequate to understand

Effect of antecedent rainfall on runoff during low-intensity rainfall

Journal of Hydrology, 1986
The objective of this study was to determine the relative significance of several rainfall characteristics to the occurrence and magnitude of runoff from small (< 300 ha) watersheds during very low-intensity rainstorms (maximum rainfall intensities < 15 mm/hr).
