Using Multi-Spectral Remote Sensing for Flood Mapping: A Case Study in Lake Vembanad, India

open access: yesRemote Sensing, 2023
Water is an essential natural resource, but increasingly water also forms a threat to the human population, with floods being the most common natural disaster worldwide. Earth Observation has the potential for developing cost-effective methods to monitor

Exposure of Loggerhead Sea Turtle Nests to Waves in the Florida Panhandle

open access: yesRemote Sensing, 2021
Wave wash-over poses a significant threat to sea turtle nests, with sustained exposure to waves potentially resulting in embryonic mortality and altered hatchling locomotor function, size, and sex ratios.

Utility of silicone filtering for diffusive model CO2 sensors in field experiments [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2013
Installing a diffusive model CO2 sensor in the soil is a direct and useful method to observe the time variation of gas CO2 concentration in soil. Furthermore, it requires no bulky measurement system.

Measuring Floodplain Inundation Using Diel Amplitude of Temperature

open access: yesSensors, 2020
Assessment of inundation patterns across large and remote floodplains is challenging and costly. Inexpensive loggers that record the damping of the diel amplitude of temperature (DAT) when submerged compared to overlying air can indirectly indicate ...

Application of Hybrid Prediction Methods in Spatial Assessment of Inland Excess Water Hazard

open access: yesISPRS International Journal of Geo-Information, 2020
Inland excess water is temporary water inundation that occurs in flat-lands due to both precipitation and groundwater emerging on the surface as substantial sources.

High-Resolution Urban Flood Forecasting by Using a Coupled Atmospheric and Hydrodynamic Flood Models

open access: yesFrontiers in Earth Science, 2020
Flood forecasting is one of the most significant tools for reducing flood risk and avoiding the loss of life To solve the problem of low resolution and the short lead time of the traditional urban flood forecasting method, this work develops a novel high-

Mapping Forested Wetland Inundation in the Delmarva Peninsula, USA Using Deep Convolutional Neural Networks

open access: yesRemote Sensing, 2020
The Delmarva Peninsula in the eastern United States is partially characterized by thousands of small, forested, depressional wetlands that are highly sensitive to weather variability and climate change, but provide critical ecosystem services. Due to the

Effective real-time forecasting of inundation maps for early warning systems during typhoons

open access: yesMATEC Web of Conferences, 2018
Accurate forecasts of hourly inundation depths are essential for inundation warning and mitigation during typhoons. In this paper, an effective forecasting model is proposed to yield 1- to 6-h lead-time inundation maps for early warning systems during ...
