Can Aquifer Replenishment Save Sinking Cities like Jakarta?
Water BodiesJakarta is one of the world’s fastest sinking cities. The city is sinking at an alarming rate of up to 25 centimeters per year, and it is predicted that 95% of North Jakarta will be under water by 2050. The sinking is caused by a combination of factors including excessive groundwater extraction, soil compaction, and
What is the Current Atmospheric Concentration of Carbon Dioxide?
Energy & ResourcesCarbon dioxide (CO2) is a naturally occurring gas in the atmosphere. However, human activities such as the burning of fossil fuels and deforestation have significantly increased the concentration of CO2 in the atmosphere over the past century. This increase in atmospheric CO2 is a major contributor to global warming and climate change. It is therefore
Resolving the ‘UZ Column Shorter Than the Initial Water Depth’ Error in MIKE-SHE Model Runs
Modeling & PredictionMIKE-SHE is a popular integrated hydrologic model for simulating water flow and transport in watersheds. It is widely used in the geosciences for modeling hydrologic processes such as groundwater recharge and discharge, surface water runoff, and soil moisture dynamics. However, MIKE-SHE model runs can sometimes generate errors, one of which is the “UZ column shorter
The Carbon Footprint of War: Quantifying the Release of Carbon Dioxide into the Atmosphere
General Knowledge & EducationWar has been a constant presence throughout human history, with devastating consequences for both human life and the environment. One of the less discussed impacts of war is the amount of carbon dioxide (CO2) released into the atmosphere during armed conflict. CO2 is a greenhouse gas that contributes to climate change, and the release of
Troubleshooting Water Level Exceedance Errors in MIKE-SHE and MIKE-HydroRiver Models: A Guide for Earth Scientists
Modeling & PredictionMIKE-SHE and MIKE-HydroRiver are popular hydrological models used by geoscientists to simulate water flow and transport in river basins. However, when running these models, users may encounter errors such as “Water level exceeded maximum…more than 4.0000 times cross section height”. This error message indicates that the water level in the simulation has exceeded the maximum
Improving Wetland Evaporation Estimates: Enhancing the WRSM-Pitman Model with Accurate Alpha Calculation
Modeling & PredictionWetlands play an important role in the global water cycle and are critical for maintaining the ecological balance of surrounding areas. Measuring and estimating evaporation from wetlands is an important aspect of understanding the water balance in these ecosystems. The Wetland Surface Area Model (WSAM) is widely used to estimate evaporation from wetlands, but it
