Extreme precipitation and flooding frequency associated with global climate change are expected to increase worldwide, major consequences in floodplains areas susceptible flooding. The purpose of this review was examine the effects events on changes soil properties their agricultural production. Flooding is caused by natural anthropogenic factors, can be amplified interactions between rainfall catchments. impacts structure aggregation altering resistance slaking, which occurs when aggregates not strong enough withstand internal stresses rapid water uptake. disruption enhance erosion sediment transport during contribute sedimentation bodies degradation aquatic ecosystems. Total precipitation, flood discharge, total main factors controlling suspended mineral-associated organic matter, dissolved particulate matter loads. Studies conducted paddy rice cultivation show that flooded reduced conditions neutralize pH but reversible upon draining soil. In soil, nitrogen cycling linked decreases oxygen, accumulation ammonium, volatilization ammonia. Ammonium primary form inorganic porewaters. floodplains, nitrate removal enhanced high denitrification intermittent provides necessary anaerobic conditions. soils, reductive dissolution minerals release phosphorus (P) into solution. Phosphorus mobilized events, leading increased availability first weeks waterlogging, generally time. Rainstorms promote subsurface P-enriched particles, colloidal P account for up 64% tile drainage water. Anaerobic microorganisms prevailing utilize alternate electron acceptors, such as nitrate, sulfate, carbon dioxide, energy production decomposition. metabolism leads fermentation by-products, acids, methane, hydrogen sulfide, influencing pH, redox potential, nutrient availability.

Saltwater Intrusion Into a Confined Island Aquifer Driven by Erosion, Changing Recharge, Sea‐Level Rise, and Coastal Flooding

Water Resources Research, Год журнала: 2024, Номер 60(1)

Опубликована: Янв. 1, 2024

Abstract Aquifers on small islands are at risk of salinization due to low elevations and limited adaptive capacity, present risks will be exacerbated by climate change. Most studies addressing small‐island saltwater intrusion (SWI) have focused homogeneous sandy one or two hydraulic disturbances. We herein investigate SWI dynamics in a layered, confined island aquifer response multiple environmental perturbations related change, with considered tandem. Our field modeling work is based an that provides the drinking water supply for Indigenous community Atlantic Canada. Observation well data electrical resistivity profiles were used calibrate numerical model (HydroGeoSphere) coupled groundwater flow salt transport. The calibrated was simulate impacts change including sea‐level rise (SLR), storm surge overtopping, changing recharge, erosion. Simulated conditions resilient surges because confining layer prevented deeper leaching. However, reduced recharge erosion resulted wedge migration 170 110 m, respectively when individually, up 295 m (i.e., into wellfield) together. Despite conditions, SLR 55 as pressures not sufficient resist movement. This first study harness integrated, surface‐subsurface hydrologic assess effects coastal other hydroclimatic stressors aquifers, highlighting can drive extensive critical resources.

Shifting the Sands – Early Islamic Modification of the Caesarea Sandy Lowlands into Plot-and-Berm Water-Harvesting Agroecosystem

Environmental Archaeology, Год журнала: 2024, Номер unknown, С. 1 - 20

Опубликована: Фев. 7, 2024

During the Early Islamic period, several emerging agricultural innovations enabled cultivation of summer crops in unproductive Mediterranean lands. This necessitated development water harvesting methods. study delves into creation Plot-and-Berm (P&B) agroecosystem along sandy coast Caesarea, Israel. From early tenth century to mid-twelfth century, coeval later part period and beginning Crusader a 1.5 km2 P&B was constructed maintained. Remarkably, this system still dominates landscape. The agroecosystem's expansion controlled by regional hydrological, geological, climatic factors. Anthropogenic sedimentary units include anthrosol found within plots anthrosediment berms with densely added refuse. Sedimentological mineralogical analysis unveils additives calcitic fine-grains, likely originating from nearby kilns. arrangement these fine grains amidst quartz particles fills pore spaces, reducing hydraulic conductivity natural sand. Similar other systems, morphological sedimentological adaptations were employed sustain pattern annual crop yields, capturing rainfall for during rainy season, while high groundwater levels facilitated cultivation.

Local and Remote Storm Surge Contributions to Total Water Levels in the Gulf of St. Lawrence During Hurricane Fiona

Journal of Geophysical Research Oceans, Год журнала: 2023, Номер 128(8)

Abstract Post‐tropical Hurricane Fiona generated a large storm surge that resulted in pronounced flooding and coastal erosion Atlantic Canada September 2022. In this study we apply regional barotropic model the Gulf of St. Lawrence, semi‐enclosed sea, to demonstrate method evaluating different contributions total water levels. These include over ocean, by cyclonic winds gulf, tides. The results indicate highest occurred southeastern region, combination locally remotely components. entered from ocean was greater than gulf; however, these were not phase. To investigate case where local remote surges are coincident, shift wind field relative timing boundary conditions find near “perfect storm” with significantly higher elevations. findings highlight importance basin morphology controlling interactions components, approach can be applied simulate range storm‐driven hazard outcomes for future extreme events.
