The Iraqi Western Desert (IWD) is characterized by enormous geodiversity types in different geological aspects; including geomorphology, lithology, structural geology, mineral deposits, karst forms, and geological hazards. Within each of the mentioned aspects, different forms of different shapes, sizes, and origins can be seen in different parts of the IWD, which we divided into 4 parts, among them 11 main types and 25 sub-types. We have studied geological maps of different scales (1:100000 and 1:250000), interpreted satellite images, and reviewed tens of published articles, books, and scientific reports, besides field visits which lasted for tens of years to conduct the current research. Tens of examples are presented, which confirm geological Geodiversity in the IWD including many field photos and satellite images, as best available. We also presented a satellite image of the IWD and marked 54 locations of different types of geodiversity including ex-situ and in-situ. Locally, detailed explanations are given for some significant forms and/ or features to present their types, origins, and modes of development.

Water balance as a technique is considered one of the means that is relied upon in solving significant hydrological problems. The soil and water assessment tool (SWAT) model was used in this study to assess the water balance in the Wadi Al-Mohammadi basin located at the eastern edge of the Western Desert. Digital elevation model, soil data, Land use - Land cover, and climate data represent the most important requirements for the SWAT model's input as a database. The Wadi Al-Mohammadi basin delineation results show the overall drainage area was 2286.8 km2 with seven sub-basins. The trend line of climate data indicates a clear increase in the total rainfall, relative humidity, temperature, and solar radiation from 1990-2020, while the wind speed decreased during the observed period. The average monthly hydrological components (precipitation, actual evapotranspiration, surface runoff, lateral flow, and deep aquifer recharge) representing the basin's water balance are 68.8 mm, 67 mm, 2.03 mm, 0.02 mm, and 0 mm, respectively.

One of new method to improve the bearing capacity of weak soil is by using geosynthetic reinforcement materials that has become more common in past 40 years for a number of applications to reduce the cost of maintences by increasing design life. This study concerned with the behavior of weak soil and the amount of settlement that happened when the soil exposed to different weight load with different number of blows . Field and laboratory tests done to calculate soil settlement. For experimental tests a model with dimension (150×75×75cm) has been manufactured, clayey silty sand soil in model exposed to different dynamic weight by using load with ( 4.5kg), load with (7.5kg) and load with (10kg). Each load strick the soil with 9 5 and 10) blows during an experiment for each dynamic load. 12 Laboretory experiments were conductedon 38 test points, 6 experiments done on soil without geogrid and 6 experiments done on soil with geogrid that included 19 test point for each case. The experiments tests show that by increasing the weight load and increasing in number of blows settlement increase in both cases ( without and with geogrid). The experiments show that by using geogrid the settlement decrease comparison with the amount of soil settlement without geogrid. By using geogrid and exposed to weight loads ( 4.5, 7.5 and 10kg.) with No. of blows = 5 the average percent in settlement decrease 1.2, 2.1,1.7%) and with No. of blows =10 for the same loads the average percent of settlement decrease (1.8, 2.7, 2.7%).
