Landslide susceptibility mapping using machine learning algorithms and comparison of their performance at Abha Basin, Asir Region, Saudi Arabia

2020-06-22 08:56:08 | Keywords Landslide susceptibility; MLA,

The current study aimed at evaluating the capabilities of seven advanced machine learning techniques (MLTs), including, Support Vector Machine (SVM), Random Forest (RF), Multivariate Adaptive Regression Spline (MARS), Artificial Neural Network (ANN), Quadratic Discriminant Analysis (QDA), Linear Discriminant Analysis (LDA), and Naive Bayes (NB), for landslide susceptibility modeling and comparison of their performances. Coupling machine learning algorithms with spatial data ... Read more

Sinkholes induced by uncontrolled groundwater withdrawal for agriculture in arid Saudi Arabia. Integration of remote-sensing and geophysical (ERT) techniques

2020-03-03 08:34:27 | Keywords Geophysics;, Human-induced sinkhole, Aquifer over-exploitation,

Recently, an increasing number of sinkholes related to cavernous karst bedrock has been documented in the Kingdom of Saudi Arabia (KSA). One of the most hazardous areas is Al Jouf region, with an average annual rainfall below 35 mm. Here, crop fields irrigated with groundwater have experienced a very rapid expansion. Limited hydrogeological data indicate that the over-exploitation of the ... Read more

A Flood Risk Management Program of Wadi Baysh Dam on the Downstream Area: An Integration of Hydrologic and Hydraulic Models, Jizan Region, KSA

2020-02-03 20:01:01 | Keywords dam failure; inundation;, flood hazard; management;, Baysh; KSA,

For public safety, especially for people who dwell in the valley that is located downstream of a dam site, as well as the protection of economic and environmental resources, risk management programs are urgently required all over the world. Despite the high safety standards of dams because of improved engineering and excellent construction in recent times, a zero-risk guarantee is ... Read more

Agriculture Sprawl Assessment Using Multi-Temporal Remote Sensing Images and Its Environmental Impact; Al-Jouf, KSA

2019-08-02 14:39:07 | Keywords sinkholes, GIS; aquifer, Landsat images, agriculture mapping;,

In this paper, multispectral and multi-temporal satellite data were used to assess the spatial and temporal evolution of the agriculture activities in the Al-Jouf region, Kingdom of Saudi Arabia (KSA). In the current study, an attempt was made to map the agriculture sprawl from 1987 to 2017 using temporal Landsat images in a geographic information system (GIS) environment for better ... Read more

Statistical Analysis of Rainfall Patterns in Jeddah City, KSA: Future Impacts

2019-08-04 07:43:04 | Keywords rainfall patterns; floods;, impacts; Jeddah; KSA;, Statistical analysis,

Recently, the Kingdom of Saudi Arabia (KSA) has been facing significant changes in rainstorm patterns (rainstorm intensities, frequencies, distributions) causing many flash flood events. The city of Jeddah is located in a coastal plain area, in the middle of the western side of the KSA, which represents a clear case of changing rainstorm patterns. Jeddah has been hit by many ...
