A comparative study of the estimation methods for NRCS curve number of natural arid basins and the impact on flash flood predications
There are various methods to estimate the curve number (CN) for flood studies. In the ungauged basins, hydrologists rely on the use of an NRCS-CN table called (CNdesign). The CNdesign, in this study, is estimated...

Effect of reservoir models and climate change on flood analysis in arid regions
Dams are built in arid regions across watersheds for flood control among other purposes. Capacity-elevation (C-E) curves are vital for reservoir routing and dam operation. Different models are available for re...

Modeling annual rainfall time series in Saudi Arabia using first-order autoregressive AR(1) model
The objective of this paper is to develop a forecasting model for the annual rainfall depth in Saudi Arabia (SA). The annual rainfall data of four stations are used as a pilot study. The coefficient of variati...

Solute transport model for groundwater contamination in Wadi Bani Malik, Jeddah, Saudi Arabia
Groundwater is susceptible to pollutants. Contamination occurs when human products such as gasoline, oil, and sewage get into the groundwater and cause it to become unsafe for human use. In the last 15 years, ...

The impact of rainfall distribution patterns on hydrological and hydraulic response in arid regions: case study Medina, Saudi Arabia
Rainfall distribution patterns (RDPs) are crucial for hydrologic design. Hydrologic modeling is based on Soil Conservation Services (SCS) type RDPs (SCS type I, IA, II, and III). SCS type II method is widely used...

Empirical equations for flood analysis in arid zones: the Ari-Zo model
Water resources all over the world are facing several problems such as scarcity, pollution, climate change, and global warming. Arid zones especially suffer from either severe drought or severe floods. Scienti...

A Markov Chain Model for Subsurface Characterization: Theory and Applications
This paper proposes an extension of a single coupled Markov chain model to characterize heterogeneity of geological formations, and to make conditioning on any number of well data possible. The methodology is ...
