The nature and extent of bomb tritium remaining in deep vadose zone: A synthesis and prognosis (2024)
Journal Article
Huang, Y., Evaristo, J., Li, Z., Chun, K., Sutanudjaja, E. H., Cardenas, M. B., …van Genuchten, M. T. (in press). The nature and extent of bomb tritium remaining in deep vadose zone: A synthesis and prognosis. Vadose Zone Journal, https://doi.org/10.1002/vzj2.20304

Tritium present in deep vadose zones is a useful tracer for estimating groundwater recharge, but its full utility is constrained by not knowing where and for how long the tritium tracing method remains applicable. We obtained 44 tritium profiles from... Read More about The nature and extent of bomb tritium remaining in deep vadose zone: A synthesis and prognosis.

The spatial configuration of local climate zones reveals effects on wayfinding in human walking (2023)
Journal Article
Fan, P. Y., Chun, K. P., Tan, M. L., Mah, D., Mijic, A., Strickert, G., & Yetemen, O. (2023). The spatial configuration of local climate zones reveals effects on wayfinding in human walking. PLoS ONE, 18(9), e0289780. https://doi.org/10.1371/journal.pone.0289780

The importance of easy wayfinding in complex urban settings has been recognized in spatial planning. Empirical measurement and explicit representation of wayfinding, however, have been limited in deciding spatial configurations. Our study proposed an...

Identifying the impacts of land-use spatial patterns on street-network accessibility using geospatial methods (2023)
Journal Article
Fan, P. Y., Chun, K. P., Mijic, A., Tan, M. L., Zhai, W., & Yetemen, O. (in press). Identifying the impacts of land-use spatial patterns on street-network accessibility using geospatial methods. Geographical Analysis, https://doi.org/10.1111/gean.12374

While the land use-street network nexus is well acknowledged, evidence for the one-way impacts of land-use patterns on street accessibility is still inadequate. The measurements of land-use patterns and street accessibility lack systematic knowledge....

The merit of the North Sea-Caspian pattern in explaining climate variability in the Euro-Mediterranean region (2023)
Journal Article
Çağlar, F., Yetemen, O., Chun, K. P., & Sen, O. L. (2023). The merit of the North Sea-Caspian pattern in explaining climate variability in the Euro-Mediterranean region. International Journal of Climatology, 43(10), 4648-4661. https://doi.org/10.1002/joc.8108

Teleconnection patterns are one of the key features to understanding high-frequency natural climate variability. The North Sea-Caspian Pattern (NCP) was identified as a middle tropospheric dipole and its hydroclimatological implications have been sub...

Influence of hillslope aspect on a cinder cone evolution: The Sandal Divlit example, Kula, Turkey (2023)
Presentation / Conference
Yetemen, O., Avcioglu, A., Ozcan, O., Simsek, I., Kolbuken, M., Yeo, I., …Sen, O. L. (2023, April). Influence of hillslope aspect on a cinder cone evolution: The Sandal Divlit example, Kula, Turkey. Poster presented at EGU General Assembly 2023, Vienna, Austria

Microclimatic variations in semi-arid ecosystems can cause topographic asymmetry over geologic time scales due to uneven distribution of incoming solar radiation as a function of slope aspect. This phenomenon has long been recognized in geomorphology... Read More about Influence of hillslope aspect on a cinder cone evolution: The Sandal Divlit example, Kula, Turkey.

Investigating links among heatwaves, precipitation, and land use types using the convection-permitting model in the Southwest UK for the 2022 boreal summer (2023)
Presentation / Conference
Chun, K., Ezber, Y., Toker, E., Reboita, M., Rocha, R., Risanto, B., …Castro, C. (2023, April). Investigating links among heatwaves, precipitation, and land use types using the convection-permitting model in the Southwest UK for the 2022 boreal summer

To improve sub-seasonal forecasts, different global initiatives generate continental convection-permitting simulations for resolution less than 10 kilometres for multiple decades. These simulations, however, are based on land use maps with only singl...

Allometric relations between DBH and sapwood area for predicting stand transpiration: Lessons learned from the Quercus genus (2023)
Journal Article
Schoppach, R., Chun, K., & Klaus, J. (2023). Allometric relations between DBH and sapwood area for predicting stand transpiration: Lessons learned from the Quercus genus. European Journal of Forest Research, 142, 797–809. https://doi.org/10.1007/s10342-023-01558-9

Catchment-scale transpiration is commonly determined by the use of sap-flow sensors, and its quantification, which is critical for water and forest management, relies crucially on the total catchment’s sapwood area (As). Species-specific allometric r... Read More about Allometric relations between DBH and sapwood area for predicting stand transpiration: Lessons learned from the Quercus genus.
