“…Recent research has shown that thermal data has the potential to be used to gain information on groundwater discharges across large spatial scales. Such information for example might include the localization of submarine groundwater discharge [9][10][11][12][13] and the respective quantification [14][15][16]. Moreover, it is possible to infer groundwater discharge amounts based on a linear [16] or logarithmic [14] regression analysis between the thermal plume area induced by discharge and in situ measured discharge volumes.…”

Abstract:A qualitative and quantitative monitoring of groundwater discharge was conducted based on an airborne thermal campaign undertaken along the north-western coast of the Dead Sea in January 2011 to contribute to the relatively scarce information on groundwater discharge to date in the region. The application of airborne thermal data exploits thermal contrasts that exist between discharging groundwater and background sea surface temperatures of the Dead Sea. Using these contrasts, 72 discharge sites were identified from which only 42 were known from previous in situ measurements undertaken at terrestrial springs by the Israel Hydrological Service. Six of these sites represent submarine springs and at a further 24 locations groundwater appears to seep through the sediment. Although the abundance of groundwater seepage sites suggests a significant, but so far unknown groundwater source, the main contribution appears to originate from

“…Infrared thermography has already been applied in many hydrological studies (e.g. Cardenas et al, 2008;Danielescu et al, 2009;de Lima and Abrantes, 2014a, b;de Lima et al, 2014;Mejías et al, 2012;Pfister et al, 2010;Schuetz et al, 2012). As far as we know, the innovative application of this technology proposed here is a first attempt for characterizing raindrops' size using thermography.…”

Abstract:The infrared thermography has been successfully applied as a tool for high resolution imaging in different hydrological studies. This exploratory experimental study aimed at evaluating the possibility of using infrared thermography to determine the diameter of raindrops. Rain samples are collected on a pre-heated acrylic board, which is exposed to rain during an instant, and thermograms are recorded. The area of the thermal stains ("signatures" of the raindrops) emerging on the board is measured and converted to drop diameters, applying a calibration equation. Diameters of natural raindrops estimated using this technique were compared with laser disdrometer measurements; the Nash-Sutcliffe efficiency coefficient was used for evaluating the match between the resulting histograms of drop size distribution. Results confirm the usefulness of this simple technique for sizing and counting raindrops, although it is unsatisfactory in light rain or drizzle.

“…The recharge rate is one of the basic parameters in consumption management and maintenance of these resources (Hartmann et al 2014). Recharge of an aquifer can be defined as the annual average volume that is usually in the form of resources or the average annual input as well as a percentage of precipitation commonly known as 'rate of recharge' or 'effective infiltration' (Mejías et al 2012;Andreo et al 2008).…”

Zato raziskava z uporabo metode APLIS, ki temelji na GIS, raziskuje vodonosnike v provinci Severni Horasan v Iranu. Pri tem smo upoštevali več pomembnih hidrogeoloških parametrov, ki vplivajo na napajanje vodonosnika, vključno z nadmorsko višino, naklonom, litologijo, tipom tal in infiltracijo. Za vsakega od parametrov smo pripravili informacije v ustreznih oblikah. Po obdelavi in integraciji podatkov smo izračunali hitrost polnjenja vodonosnika. Različne regije smo ustrezno ovrednotili. Rezultati kažejo, da se v kraških formacijah Severnega Horasana letne povprečne vrednosti v 30-letnem časovnem obdobju gibljejo med 103 mm in 362 mm, s povprečno vrednostjo 192 mm. Najmanjše, najvišje in povprečne stopnje polnjenja vodonosnika v študijskem območju so 42-, 73-in 54-odstotne. Tudi potencial polnjenja vodonosnika je v 83-odstotnih kraških formacij ocenjen kot zmeren, za preostale predele je ocenjen kot visok. Območja z nizkim potencialom polnjenja so povezana z nižje ležečimi zakraselimi apnenci in dolomiti, višje ležeča območja predstavljajo apnenci in dolomiti z višjim potencialom polnjenja. Ključne besede: upravljanje podzemnih vodnih virov, napajanje, APLIS, GIS, kras, Severni Horasan. In order to optimize consumption, maintenance and control of underground water, an estimation of the groundwater recharge is highly important. Therefore, this research investigates the aquifers in North Khorasan province using APLIS (Applied Physics Laboratory Ice Station) based on a GIS. For this purpose, several significant hydrogeological parameters affecting groundwater recharge including altitude, slope, lithology, soil type and infiltration are considered. Therefore, corresponding layers for these parameters were provided and prioritized. In the end and after integrating the data, the recharge rate was measured qualitatively and different regions were mapped accordingly. The results indicate that the annual average values on a 30-year timescale in karst formations of the North Khorasan vary between 103 mm and 362 mm, with the mean value of 192 mm. Minimum, maximum and mean recharge rates of aquifer in the study area are 42 %, 73 % and 54 %, respectively. Also, aquifer recharge potential in 83 % of the karst formations is moderate while it is high for the remaining. Low recharge regions correlate to lower karst limestone and dolostone areas in the lower altitudes while high recharge regions represent upper karst limestone and dolostone areas, especially in the high altitudes.
