Variations in Water Storage Capacity of a Mountain Peatland with Complex Stratigraphy
… as fens. Understanding how fens influence water storage and water release is essential for better predicting water availability as the climate changes. Peatlands located in mountain regions tend to have a complex soil profile due to the geomorphologically dynamic environment. There is …

Dam dimensions and surface porosity affect the water storage capacity of Beaver dam analogs compared to natural Beaver dams
… restoration strategies. My study compares water retention by Beaver Dam Analogs (BDAs) to natural beaver dams and undammed control reaches. I compared how dam dimensions affect the hydraulic performance of both BDAs and beaver dams, revealing gaps in research on their comparative …

Bryophytes in the hydrological cycle and climate change implications : A case study of La Réunion cloud forest
Bryophytes are able to intercept atmospheric water over the entire surface of their shoot and, once intercepted, this water forms a vital part of the hydrological cycle of their surrounding ecosystems. To investigate the role of bryophytes in the hydrological cycle, our study, conducted in the …

Application of Remote Sensing and GIS in Monitoring Land Use and Land Cover Change in the Nandoni Dam Basin
… and severe flood damages, which reduces water storage capacity and economic tourism activities in dam basins. The challenges of land use activities have highlighted the need to monitor LULC changes in the Nandoni Dam basin. Remote sensing and Geographical Information Systems (GIS) methods …

Optimal Conjunctive Management of Supplemental Irrigation Reservoirs and Cropland
Most claypan soil areas have inadequate groundwater supplies to provide wells for irrigation. Therefore, the establishment of reservoirs for storing rainfall and runoff water, seems to be the most likely source of irrigation water in such areas. However, the storage of runoff water for later reuse …

Sustainable water resources development in Kuwait : an integrated approach with comparative analysis of the case of Singapore
This thesis assesses the water resource status of Kuwait and Singapore, both countries considered as water scarce. The institutional aspect of Integrated Water Resource Management (IWRM) efforts in both countries is closely examined at international, regional, national and administrative levels. …

Ceramic filter manufacturing in Northern Ghana : water storage and quality control
In 2009, Pure Home Water (PHW), a Ghana based non-profit organization working to provide affordable and safe drinking water to people in the Northern Region of Ghana, began the construction of a ceramic pot filter (CPF) factory near the city of Tamale. By 2011, the factory had the molds, supplies, …

Modeling of water table profile for a subirrigation system and evaluation of reliability of drainmod for the Lower Fraser Valley
… Valley of British Columbia under different water regimes with DRAINMOD and the results were compared with data obtained from conventional subsurface drainage and subirrigation field experiment at Boundary Bay in the Lower Fraser Valley. Predicted and measured water table depth were compared …

Restoration of lowland raised bogs damaged by peat extraction - with particular emphasis on Sphagnum regeneration.
… support floating rafts of bog vegetation. 2. The water storage capacity of cut-over bog surfaces is low compared with undisturbed bog and blocking drains in a peat field at Thorne Moors, S. Yorks, was insufficient to prevent water-table instability. Experiments suggest this may severely inhibit …

Effects of climate and forest management on the water and nitrogen status of European beech regeneration and understorey vegetation
… duration in near future. Due to the low adaptive capacity of forest ecosystems to rapid climate changes, high priority is given to the assessment of their responses. Particularly, studies on forests dominated by the drought susceptible European beech, especially when grown on limestone-derived …

Aqua + Culture: Intergrating Fish, Farming, and Flood-control Systems on Four Mile Run
… by protecting crops on the dike and increasing water storage capacity with ponds. Duplicating the system to other parts of world seems impossible because of the weather conditions, technical requirements to operate the system and its intensive labor requirement. However, in a broader view, it …

Experimental studies of magmatic differentiation and the effects of water on phase stability
… of magmas. A major focus is the effect of water on the stability of mineral phases, and how this affects both the differentiation of magmas and the modification of the upper mantle by hydrous fluid release during subduction. Chapter 1 models the crystallization of the asteroid Vesta, which …

Water Relations of Ponderosa Pine in Contrasting Environments: Implications for Global Climate Change
… most relevant allometric component controlling water transport is the ratio of biomass allocated to leaves versus sapwood (AL/AS). Within Pinus, trees decrease ALAS in response to rising VPD. Thus, rises in air temperature and VPD may profoundly alter the water relations of trees and forests. I …

Assessing impacts of climate change on the hydrology of the Nile River
… 2050, approaching one billion. The increase in water demand associated with this burgeoning population fuels an ongoing water conflict between the riparian countries. Uncertainty regarding potential future changes in the flow of the Nile River as a result of climate change adds further stress to …

A framework for determining remote sensing capabilities for ecosystem services valuation
Nature provides vital services—clean water, air purification, and climate regulation—to human societies thanks to the "natural capital" like forests and lakes on our planet. Accurately measuring and valuing these ecosystem services is crucial for informed economic and development decisions. Remote …

The effect of iron on the stability, water content and compressibility of mantle silicates – Implications for a hydrous Martian interior
… silicates (DHMS) in the Martian interior and the water storage potential of a hydrous Martian mantle are evaluated. 1. The effect of iron on the water content of ringwoodite The results show that the water contents of Fe-rich ringwoodites of about 0.4-0.7 wt% H2O are considerably reduced compared …
