“…Although some geo-environmental hazards of the Damt District were regionally studied as a part of the WYVP, by few authors (e.g., Arya et al, 1985;Dowgiallo, 1986;Al-Sinawi andAl-Aydrus, 1999, Al Dafiry, 2005;Wagner and Mattash,2007, Minissal et al, 2007and Al Derwish and Al Matary, 2011. none of these studies discussed the integration of those hazards and their interference with human activities impacts.…”

The Damt hot springs area has a high vulnerability to geohazards (e.g., earthquake, mass wasting, and flash flood hazards). It is located at the southeastern escarpment of the Western Yemen Volcanic Plateau (WYVP) which is considered as the most volcanic and tectonic active provenience in Yemen. The relatively high risk of integrated factors (e.g., annual rainfall, steep slopes, and potential seismotectonic activities in the study area) has caused it to be an inherently susceptible area. Therefore, this study attempts to assess the geo-environmental conditions and factors and their implication on triggering the geohazards in Damt District. An integrated approach using field observation, remote sensing analysis, and geospatial data analysis was applied to reveal geohazard prone zones. To better understand the causative factors controlling the geohazards and their environmental impacts, topographical, geological, and hydrological characteristics were mapped and investigated. The common anthropogenic factors including human interference through, excavation of the slopes mainly for house building and mountain terraced cultivation, inconvenient hot spring water utilization, and habitation patterns around the travertine cones area was integrated with the causative factors to increase the risk potentiality of geoenvironmental problems. Based on spatial integration of all contributing factors, most of the scattered hanged villages in the high relief, steep-sloped, highly weathered mountainous volcanic zone is prone to serious geohazards. In this respect, several mitigation measures, including the determination of several dams' localities, are proposed to protect the urban area and enhance the water resources.

“…Thermal springs are classified as (-non-volcanic: heat and water supply are not directly related to volcanoes -medium: excess heat is caused by abnormally high ground temperature gradients resulting from volcanic activity, but the water is completely meteoritic -volcanic: characterized by excess heat, a lot of mineral content and part of the water from a volcanic source [35]. Since water is the most valuable resource in the long run with the high population growth and expansion of economic activities and the increasing use of groundwater for irrigation, bathing, local supply [3]. Thermal springs are natural resources, and if they are optimally developed, they can make a significant contribution at the local and economic levels [27].…”

This research aims at determining some of the physicochemical properties of hot springs in the areas of (Shara’a and Kirsh) Lahij Governorate. 45 samples were collected for 15 sites. The following parameters were measured: acidity number (pH), total dissolved solids (TDS), electrical conductivity (EC), total hardness (TH), Calcium Hardness (TH.Ca), Magnesium Hardness (TH.Mg), Alkalinity, Calcium (Ca2+), Magnesium (Mg2+), Sodium (Na+), Potassium (K+), Bicarbonate (HCO3-), Sulfate (SO42-), Nitrate (NO3-), Fluoride (F-), Chloride, and (Cl-), Sodium Absorption Ratio (SAR). The results showed that the values of Total Dissolved Solids (TDS), Electrical Conductivity (EC), Alkalinity, Sodium, Potassium, Sulfate and Fluoride were higher than the maximum allowable limits of the World Health Organization (WHO) for drinking water by 100%, while the concentration of Chloride in Krish area and alkalinity in Shara'a area exceeded WHO limits by 100%. As for the rest of the parameters, they were less than the permissible limit according to the standard specifications. Also, the results showed that the water of Shara'a and Kirsh hot springs has temperatures (oC) of 60 and 62.5 respectively. The waters from the hot springs in Shara'a and Krish are thus not fit for human consumption. The study recommends the use of hot spring water for recreational purposes should be closely monitored. It is thus important that the physical and chemical composition of hot springs should be monitored on a regular basis. Finally, the study recommends a comprehensive study of the chemical and therapeutic properties of hot springs water, as well as the geological characteristics of the study area.
