Glacial Processes and Landforms (2022)
Book Chapter
Evans, D., & Evans, I. (2022). Glacial Processes and Landforms. In T. Burt, A. Goudie, & H. Viles (Eds.), The History of the Study of Landforms or the Development of Geomorphology. Volume 5: Geomorphology in the Second Half of the Twentieth Century (333-377). The Geological Society. https://doi.org/10.1144/m58-2021-17

From 1965 to 2000 glacial geomorphology became increasingly specialized and developed significantly due to technological improvements, particularly in remote sensing, surveying and field-based glaciological process studies. The better understanding o... Read More about Glacial Processes and Landforms.

The erosion of glaciated mountains: evidence from hypsoclinometry (2019)
Journal Article
Evans, I. S. (2019). The erosion of glaciated mountains: evidence from hypsoclinometry. Revista de geomorfologie, 21(1), 5-14. https://doi.org/10.21094/rg.2019.006

Mountain glaciation involves the erosion of cirques and troughs, which increase steep slopes but also produce gentle slopes in cirque floors and trough floors. This is expected to increase the variability of slope gradients at related altitudes. Taki... Read More about The erosion of glaciated mountains: evidence from hypsoclinometry.

The dynamics of mountain erosion: cirque growth slows as landscapes age (2019)
Journal Article
Barr, I. D., Ely, J. C., Spagnolo, M., Evans, I. S., & Tomkins, M. D. (2019). The dynamics of mountain erosion: cirque growth slows as landscapes age. Earth Surface Processes and Landforms, 44(13), 2628-2637. https://doi.org/10.1002/esp.4688

Glacial cirques are widely used palaeoenvironmental indicators, and are key to understanding the role of glaciers in shaping mountain topography. However, notable uncertainty persists regarding the rate and timing of cirque erosion. In order to addre... Read More about The dynamics of mountain erosion: cirque growth slows as landscapes age.

Geomorphic features of Quaternary glaciation in the Taniantaweng Mountain, on the southeastern Qinghai-Tibet Plateau (2019)
Journal Article
Zhang, W., Chai, L., Evans, I. S., Liu, L., Li, Y.-P., Qiao, J.-R., Tang, Q.-Y., & Sun, B. (2019). Geomorphic features of Quaternary glaciation in the Taniantaweng Mountain, on the southeastern Qinghai-Tibet Plateau. Journal of Mountain Science, 16(2), 256-274. https://doi.org/10.1007/s11629-018-4977-3

We present geomorphological evidence for multiple glacial fluctuations during the Quaternary in the Taniantaweng Mountain, which is situated at the transition zone of the southeastern Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau. To reconstru... Read More about Geomorphic features of Quaternary glaciation in the Taniantaweng Mountain, on the southeastern Qinghai-Tibet Plateau.

Allometric development of glacial cirque form: Geological, relief and regional effects on the cirques of Wales (2006)
Journal Article
Evans, I. (2006). Allometric development of glacial cirque form: Geological, relief and regional effects on the cirques of Wales. Geomorphology, 80(3-4), 245-266. https://doi.org/10.1016/j.geomorph.2006.02.013

Headward and downward erosion near glacier sources, at rates exceeding fluvial erosion, is important in recent discussions of orogen development and the limits to relief. This relates to a long history of debate on how the form of glacial cirques dev...

Local aspect asymmetry of mountain glaciation: A global survey of consistency of favoured directions for glacier numbers and altitudes (2006)
Journal Article
Evans, I. (2006). Local aspect asymmetry of mountain glaciation: A global survey of consistency of favoured directions for glacier numbers and altitudes. Geomorphology, 73(1-2), 166-184. https://doi.org/10.1016/j.geomorph.2005.07.009

Understanding aspect effects on present-day glaciers provides essential background to the palaeoclimatic interpretation of reconstructed former glaciers or glacial cirques. Several factors influencing glacier mass balance vary with slope aspect: thes...

Global variations of local asymmetry in glacier altitude: separation of north-south and east-west components (2005)
Journal Article

North-south and east-west differences in firn-line altitude, equilibrium-line altitude or middle altitudes of glaciers can be separated by regression on the cosine and sine of glacier aspect (accumulation area azimuth). Allowing for regional trends i... Read More about Global variations of local asymmetry in glacier altitude: separation of north-south and east-west components.
